Description

Rear-view mirror structure

Technical Field

The invention relates to a rearview mirror structure.

Background

As described in patent document 1, a conventional mirror structure having an electric rotating unit is known, in which a mirror is automatically moved between a usable position and a storage position.

This rear-view mirror structure includes: a mirror main body part having a mirror; a mirror base projecting from the side door in the vehicle width direction; an electric rotating unit accommodated in the mirror main body. The mirror base is a portion having a base end portion and a tip end portion, extending in the vehicle width direction, and constituting an arm portion of the mirror. The mirror base is fixed to the side door at its base end, and the mirror main body is attached to the front end of the mirror base so as to be rotatable about a rotation axis extending in the vertical direction.

The mirror main body is rotated by a rotational driving force of an electric rotating unit accommodated in the mirror main body through a front end of a mirror base, and is movable between a mirror use position and a mirror storage position. The mirror use position is a position where the mirror main body protrudes outward in the vehicle width direction from the front end of the mirror base and the mirror can be visually observed from the cabin. The storage position is a position where the mirror main body extends substantially parallel to the side door.

Disclosure of Invention

Technical problem to be solved by the invention

The rear view mirror structure is a structure in which a base end portion of a mirror base is fixed to a side door and a mirror main body portion is turned around through a front end portion of the mirror base. Therefore, if the vehicle design requires the mirror base to be long in the width direction, the mirror base remains protruding from the door panel even when the mirror main body is moved to the storage position when the mirror is stored, and therefore the requirement for reducing the vehicle width when the mirror is stored cannot be sufficiently satisfied.

In addition, in the above configuration, since the electric power storage unit is housed in the interior of the mirror main body, the vertical moment generated at the position of the electric power rotating unit increases in proportion to the length of the mirror base, and therefore there is a problem that the vibration of the mirror becomes large when the vehicle travels.

Further, since the mirror main body portion accommodates the electric rotating unit therein, the mirror main body portion has a large front-rear width (i.e., a width in the front-rear direction of the vehicle), and the mirror main body portion may obstruct visibility when viewed from the cabin.

In view of the above circumstances, an object of the present invention is to provide a rearview mirror structure capable of reducing the vehicle width when the mirror is stored, suppressing the vibration of the mirror when the vehicle is traveling, and improving the visibility when the mirror is viewed from the cabin.

Means for solving the problems

In order to solve the above technical problems, the present invention provides a rearview mirror structure on a side door of a vehicle, comprising: a mirror main body having a mirror for obtaining a rearward field of view of the vehicle; a mirror base having a front end fixed to the mirror main body and a base end remote from the front end, the base end being attached to the side door such that the mirror main body and the mirror base are movable between a mirror use position where the mirror is visible from the cabin and a storage position located inside the mirror use position in the vehicle width direction; a drive unit that moves the mirror main body and the mirror base between the mirror use position and the storage position; wherein, the driving unit is arranged on the side door.

According to the above aspect, in the mirror structure including the mirror main body portion having the mirror and the mirror base in which the mirror main body portion is fixed to the front end portion, the driving unit moves the mirror base together with the mirror main body portion from the mirror use position to the storage position. Therefore, in the state where the mirror main body and the mirror base are moved to the stored position, the amount of projection of the mirror main body and the mirror base from the side door side surface to the vehicle width direction can be reduced, and therefore the vehicle width dimension can be minimized.

In addition, in this mirror structure, since the heavy drive unit is disposed in the side door, the moment in the vertical direction generated in the mirror due to the input from the road surface (i.e., the vertical vibration or the external force mainly caused by the unevenness of the road surface) during the traveling of the vehicle is reduced, and the mirror vibration can be suppressed.

Further, since the drive unit is disposed in the side door, the front-rear width of the mirror main body can be reduced as compared with a conventional mirror structure in which the drive unit is accommodated in the mirror main body, and visibility when viewed from the cabin can be improved.

In the mirror structure, it is preferable that the drive unit is disposed in the side door. This protects the drive unit from foreign objects outside the vehicle through the outer side surface of the side door.

In the above mirror structure, it is preferable that the mirror structure further includes a pivot shaft that is connected to the base end portion of the mirror base and supports the mirror main body and the mirror base so as to be rotatable between the mirror use position and the mirror storage position, wherein the pivot shaft extends from the base end portion into the side door and is pivoted by the driving means.

According to the above aspect, since the mirror device further includes the pivot shaft for rotatably supporting the mirror main body and the mirror base, the pivot shaft can be rotated by the driving means in the side door, and the mirror main body and the mirror base can be moved between the mirror use position and the mirror storage position while rotating about the pivot shaft. Therefore, the mirror main body and the mirror base can be moved between the mirror use position and the mirror storage position with a simple configuration.

In the mirror structure, it is preferable that the drive unit is disposed on an axis of the pivot shaft.

According to the above aspect, since the drive means is disposed on the axis of the pivot shaft, the structure of the power transmission system for transmitting power from the drive means to the pivot shaft can be simply and compactly configured. This makes it possible to arrange the drive unit in a limited space inside the side door.

In the above-described mirror structure, it is preferable that a through hole through which the pivot shaft passes is formed in a door plate constituting the outer side surface of the side door, and a cover member for covering a gap between the through hole and the pivot shaft from the outside of the vehicle is further provided.

According to the above aspect, the cover member covers the gap between the through hole of the door panel and the pivot shaft from the outside of the vehicle, and therefore, the appearance of the vehicle is improved, and water can be prevented from entering the door panel through the gap.

In the above mirror structure, it is preferable that the drive unit is fixed to a frame member provided in the side door and constituting a frame of the side door.

According to the above aspect, since the drive unit is fixed to the frame member constituting the side door frame, the support rigidity of the drive unit is improved.

In the above mirror structure, it is preferable that the frame member is a belt line reinforcement extending in a vehicle front-rear direction along a belt line at a lower edge of a window of the side door.

According to the above aspect, the drive unit is fixed to the beltline reinforcement generally used in the conventional door structure, whereby the above-described mirror structure can be widely applied to the conventional door structure.

In the above mirror structure, it is preferable that the beltline reinforcement is made of an aluminum extruded material.

According to the above aspect, since the belt line reinforcement is made of the aluminum extruded material, it is possible to ensure both the support rigidity of the drive unit and the weight reduction of the vehicle.

In the mirror structure, it is preferable that an inner side surface of the mirror main body portion facing the side door is inclined toward a vehicle outside with respect to a virtual line which is orthogonal to the mirror surface and passes through an inner end portion of the mirror main body portion in a plan view in a state where the mirror main body portion is located at the mirror use position.

According to the above aspect, in the state where the mirror main body is located at the mirror use position, the inner side surface of the mirror main body facing the side door is inclined toward the vehicle outer side with respect to the imaginary line orthogonal to the mirror surface in plan view, and thus the inner side surface of the mirror main body does not block the view when viewed from the cabin. This ensures the visibility as seen from the cabin to the maximum, thereby further improving the visibility.

In the mirror structure, it is preferable that the mirror main body has a thickness in the front-rear direction that decreases from a vehicle width direction intermediate position toward a vehicle width direction inner end in a plan view in a state in which the mirror main body is located at the mirror use position.

According to the above aspect, when the mirror main body is located at the mirror use position, the thickness of the mirror main body in the front-rear direction decreases from the vehicle width direction intermediate position toward the vehicle width direction inner end portion, and thus the view from the cabin is no longer blocked by the inner side surface of the mirror main body. This ensures visibility as viewed from the cabin to the maximum, thereby further improving visibility.

Effects of the invention

The invention provides a rearview mirror structure which can simultaneously and well realize the reduction of the vehicle width when the mirror is stored, the suppression of the mirror vibration when the vehicle runs and the improvement of the visibility when the vehicle is seen from a cabin.

Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 to 2 show a vehicle side door 1 to which the rearview mirror structure of the invention is applied. In the side door 1, the mirror 2 is disposed on the vehicle rear side of the pillar 4a near the belt line BL at the upper end 3a of the door panel 3. A door glass 6 is disposed in a door opening 5 surrounded by the a pillar 4 and the belt line BL.

As shown in fig. 1 to 7, the vehicle side door 1 according to the present embodiment has a mirror structure in which a mirror 2 that can be electrically driven and stored is attached to the side door 1. Specifically, the main parts of the mirror structure include a mirror main body 11 and a mirror base 12 constituting the mirror 2, and an electric rotating unit 13 as a driving unit for moving the mirror main body 11 and the mirror base 12. The electric rotating unit 13 is provided in the side door 1.

Furthermore, the mirror structure of the present embodiment further includes: a pivot shaft 24 (see fig. 11 to 12) for rotatably supporting the mirror main body 11 and the mirror base 12; a belt line reinforcement 21 which is a skeleton member inside the side door 1; a support member 22 for fixing the electric rotating unit 13 to the belt line reinforcement 21, and a cover member 27 provided on the vehicle exterior side of the side door 1.

Hereinafter, each constituent element of the mirror structure will be explained in turn.

As shown in fig. 2, the mirror main body 11 includes a mirror 14 for obtaining a rearward view of the vehicle and a housing 15. The mirror 14 is an optical mirror that reflects light, and is placed on a surface on the rear side of the housing 15 (specifically, a surface facing the rear side in the state of the mirror use position P1 in fig. 3). The housing 15 of the mirror main body 11 accommodates therein internal devices 37 such as a mirror surface adjusting unit for adjusting an angle between the vertical direction Z of the mirror 14 and the vehicle width direction Y, and a defrosting unit for the mirror 14 (see fig. 12).

The mirror base 12 is a part constituting an arm portion of the mirror 2, and includes a distal end portion 12b fixed to the mirror main body 11 and a proximal end portion 12a distant from the distal end portion 12b, as shown in fig. 3 to 6.

More specifically, the mirror main body 11 is fixed to the distal end portion 12b of the mirror base 12, and the mirror 14 extends substantially parallel to the mirror base 12.

The mirror base 12 has a base end portion 12a attached to the side door 1 so that the mirror main body 11 and the mirror base 12 can move between a mirror use position P1 where the mirror 14 can be visually observed from the cabin and a storage position P2 located inside the mirror use position P1 in the vehicle width direction Y.

In the present embodiment, a pivot shaft 24 shown in fig. 9 to 12 is coupled to the base end portion 12a of the mirror base 12, and the mirror body 11 and the mirror base 12 are supported by the pivot shaft 24 to be rotatable between a mirror use position P1 (see fig. 3 and 5) and a storage position P2 (see fig. 4 and 6).

The turning support shaft 24 extends from the base end portion 12a into the side door 1, and is turned by the electric turning unit 13.

Specifically, as shown in fig. 9 to 12, a through hole 26 is formed in a door panel 3 (outer panel) constituting an outer side surface of the side door 1. The turning support shaft 24 is coaxially coupled to an output shaft 35 (see fig. 12) of the electric turning unit 13 disposed in the space portion 20 in the side door 1 through a through hole 26 of the door panel 3.

The electric rotating unit 13 has a structure for moving the mirror main body 11 and the mirror base 12 between the mirror use position P1 and the storage position P2. Specifically, as shown in fig. 12, the electric rotating unit 13 includes a sleeve 31, a motor 32, a speed reducer 33 that reduces the speed of the torque generated by the motor 32, a torque limiter 34, and an output shaft 35 that outputs the rotational driving force. The sleeve 31 accommodates the motor 32, the speed reducer 33, the torque limiter 34, and the output shaft 35. The sleeve 31 also accommodates a rotation support shaft 24 and a bearing 36 for supporting the rotation support shaft 24 to be rotatable. Therefore, the motor 32, the reducer 33, the torque limiter 34, and the output shaft 35, which are main components of the electric rotating unit 13, are disposed on the axis of the rotating support shaft 24. The output shaft 35 is connected to the pivot shaft 24 and is rotatable integrally therewith.

When the motor 32 is operated and an excessive torque is generated at the rotation support shaft 24, the torque limiter 34 can block the transmission of the torque and suppress the load on the motor 32.

The bearing 36 is preferably a ball bearing or a roller bearing that supports the pivot shaft 24 with a small rotational resistance.

The electric rotating unit 13 is fixed to the belt line reinforcement 21 by a support member 22.

The belt line reinforcement 21 is provided in the side door 1 and is a skeleton member constituting a skeleton of the side door 1. As shown in fig. 7, the belt line reinforcement 21 is fixed to the door panel 7 (see fig. 7 and 12) inside the side door 1, and extends in the vehicle front-rear direction X along a belt line BL of a window lower end edge of the side door 1 (i.e., a lower end edge of the door opening 5 where the door glass 6 is disposed). The belt line reinforcement 21 of the present embodiment is made of an aluminum extruded material.

Specifically, as shown in fig. 8 to 12, the support member 22 includes a semi-cylindrical mounting portion 22a and a pair of fixing portions 22b provided on both sides of the mounting portion 22a in the vehicle longitudinal direction X. The housing portion 22a houses a sleeve 31 housing the electric rotating unit 13 and the rotating fulcrum 24. The pair of fixing portions 22b are fastened to the beltline reinforcement 21 by bolts 28.

In the present embodiment, as shown in fig. 9 to 12, the wire harness 25 extends from the space portion 20 in the side door 1 to the mirror main body 11, and is electrically connected to the internal device 37 (mirror surface adjusting means, etc.) inside the mirror main body 11.

Specifically, as shown in fig. 11 to 12, the beltline reinforcement 21 has a 1 st opening 21a formed at a position facing the placement portion 22a of the support member 22. Further, a 2 nd opening 31a is formed in the sleeve 31 of the electric rotating unit 13 at a position opposed to the 1 st opening 21a. The rotation support shaft 24 of the present embodiment is hollow and cylindrical, and a 3 rd opening 24a is formed in a circumferential surface thereof at a position facing the 2 nd opening 31a. Therefore, the wire harness 25 extends from the inside of the side door 1 to the inside of the pivot shaft 24 through the 1 st opening 21a of the beltline reinforcement 21, the 2 nd opening 31a of the grommet 31, and the 3 rd opening 24a of the pivot shaft 24 (refer to a portion 25a of the wire harness 25 extending upward through the inside of the pivot shaft 24 in fig. 11). The wire harness 25 is electrically connected to an internal device 37 extending through the pivot shaft 24 and the inside of the mirror base 12 to the inside of the mirror main body 11.

In the mirror structure of the present embodiment, since the mounting portion 22a of the support member 22 has a semi-cylindrical shape, even in the state where the wire harness 25 is laid as described above, the sleeve 31 can be inserted into the mounting portion 22a of the support member from above without the wire harness 25 interfering with the mounting portion 22a.

The cover member 27 covers a gap between the through-hole 26 and the pivot shaft 24 from the vehicle exterior side. Specifically, as shown in fig. 9 to 12, the sleeve 31 of the electric rotating unit 13 in which the rotating support shaft 24 is accommodated and the mounting portion 22a of the support member 22 covering the sleeve 31 are exposed to the outside of the vehicle through the through hole 26 of the door panel 3. The cover member 27 covers the sleeve 31 accommodating the rotation support shaft 24 from the outside of the vehicle and the mount portion 22a from the lower side of the base end portion 12a of the mirror holder 12, and also covers a gap between the through hole 26 and the mount portion 22a.

As shown in fig. 13, in order to improve visibility when viewed from the cabin, the mirror main body 11 of the present embodiment is configured such that, in a state in which the mirror main body 11 is located at the mirror use position P1, an inner side surface 11b of the mirror main body 11 facing the side door 1 is inclined toward the outside of the vehicle (i.e., inclined in a direction away from the side door 1) with respect to a virtual line L1 that is orthogonal to the surface of the mirror 14 and passes through an inner end 11a of the mirror main body 11 facing the side door 1 in a plan view. That is, the inner side surface 11b of the mirror body 11 extends along a line L2 extending obliquely toward the vehicle exterior side with respect to the virtual line L1, starting from the inner end 11a of the mirror body 11. In other words, in the state where the mirror main body 11 shown in fig. 13 is located at the mirror use position P1, the thickness of the mirror main body 11 in the front-rear direction X becomes smaller (tapered) from the intermediate position of the mirror main body 11 in the vehicle width direction Y toward the inner end portion 11a on the side of the side door 1 in the vehicle width direction Y in plan view.

Due to the shape of the mirror main body 11 as described above, the inner surface 11b of the mirror main body 11 does not obstruct the view from the cabin as shown in fig. 14. This ensures a wide field of view in the space S1 in front of the mirror main body 11, i.e., the space S1 surrounded by the inner end 11a of the mirror main body 11, the a pillar 4, and the waist line BL, thereby improving visibility.

For reference, in the comparative example of the present invention, as shown in the mirror 50 of fig. 15, in the configuration in which the mirror main body 51 houses the electric rotating unit (not shown), the front-rear width of the mirror main body 51 becomes larger, and therefore, as the front-rear width becomes larger, the inner side surface 51b of the mirror main body 51 will be seen in the field of view when seen from the cabin. Therefore, it is found that the visibility in the space S2 in front of the mirror main body 51, that is, the space S2 surrounded by the inner end 51a of the mirror main body 51, the a pillar 4, and the waist line BL is reduced.

(features of the present embodiment)

（1）

In the mirror structure of the present embodiment, the mirror structure on the side door 1 of the vehicle includes: a mirror main body 11 having a mirror 14 for obtaining a rearward view of the vehicle; a mirror base 12 having a front end portion 12b fixed to the mirror main body 11 and a base end portion 12a distant from the front end portion 12b, the base end portion 12a being attached to the side door 1 such that the mirror main body 11 and the mirror base 12 are movable between a mirror use position P1 at which the mirror 14 is visible from the cabin and a storage position P2 located inside the mirror use position P1 in the vehicle width direction Y; the electric rotating unit 13, i.e., a driving unit, moves the mirror main body 11 and the mirror base 12 between the mirror use position P1 and the storage position P2. As shown in fig. 7 to 10 and 12, the electric rotating unit 13 is disposed in a space 20 in the side door 1.

According to the above configuration, in the mirror structure including the mirror main body 11 to which the mirror 14 is attached and the mirror base 12 to which the mirror main body 11 is fixed to the front end portion 12b, the electric rotating unit 13 moves the mirror base 12 from the mirror using position P1 to the housing position P2 together with the mirror main body 11. Therefore, in the state where the mirror main body 11 and the mirror base 12 are moved to the storage position P2, the amount of projection of the mirror main body 11 and the mirror base 12 from the side door 1 side in the vehicle width direction Y can be reduced, and therefore the vehicle width dimension can be minimized.

In addition, in this mirror structure, since the heavy electric rotating unit 13 is disposed in the side door 1, the input from the road surface (i.e., mainly the vibration in the vertical direction Z or the external force due to the irregularity of the road surface) when the vehicle is running reduces the moment in the vertical direction Z generated in the mirror, and the mirror vibration can be suppressed.

Further, since the electric rotating unit 13 is disposed in the side door 1, the front-rear width of the mirror main body 11 can be reduced as compared with a conventional mirror structure in which the electric rotating unit 13 is accommodated in the mirror main body 11, and visibility from the cabin can be improved.

（2）

In the mirror structure of the present embodiment, since the electric revolving unit 13 is disposed inside the side door 1, the electric revolving unit 13 can be protected from foreign objects outside the vehicle and the like by the door panel 3 constituting the outer side surface of the side door 1. The electric rotating unit 13 may be disposed outside the side door 1, and in this case, a large cover member or the like for protecting the electric rotating unit 13 is required.

（3）

The mirror structure of the present embodiment further includes a pivot shaft 24, and the pivot shaft 24 is coupled to the base end portion 12a of the mirror base 12, and supports the mirror main body 11 and the mirror base 12 to be rotatable between the mirror use position P1 and the storage position P2. The turning support shaft 24 extends from the base end portion 12a into the side door 1, and is turned by the electric turning unit 13.

According to the above configuration, since the mirror main body 11 and the mirror base 12 are further provided with the pivot shaft 24 for supporting the mirror main body and the mirror base to be rotatable, the pivot shaft 24 can be rotated by the electric rotating means 13 in the side door 1, and the mirror main body 11 and the mirror base 12 can be moved between the mirror use position P1 and the storage position P2 while rotating about the pivot shaft 24. Therefore, the mirror main body 11 and the mirror base 12 can be moved between the mirror use position P1 and the storage position P2 with a simple configuration.

（4）

In the mirror structure of the present embodiment, the electric rotating unit 13 (specifically, the main components of the motor 32, the speed reducer 33, the torque limiter 34, and the output shaft 35) is disposed on the axis of the rotating support shaft 24.

According to the above configuration, since the electric rotating unit 13 is disposed on the axis of the rotation support shaft 24, the configuration of the power transmission system for transmitting power from the electric rotating unit 13 to the rotation support shaft 24 can be simply and compactly configured. This allows the electric rotating unit 13 to be installed in a limited space inside the side door 1.

（5）

In the mirror structure of the present embodiment, a through-hole 26 through which a pivot shaft 24 passes is formed in a door plate 3 constituting an outer side surface of a side door 1. The mirror structure further includes a cover member 27 that covers a gap between the through-hole 26 and the pivot shaft 24 from the outside of the vehicle.

According to the above configuration, since the cover member 27 covers the gap between the through hole 26 of the door panel 3 and the pivot shaft 24 from the outside of the vehicle, the appearance of the vehicle is improved, and water can be prevented from entering the door panel 3 through the gap.

（6）

In the mirror structure of the present embodiment, electric rotating unit 13 is fixed to a belt reinforcement 21, which is a frame member constituting a frame of side door 1 provided in side door 1.

According to the above aspect, the electric rotating unit 13 is fixed to the belt line reinforcement 21, which is a frame member constituting the frame of the side door 1, and therefore the support rigidity of the electric rotating unit 13 is improved.

（7）

In the mirror structure of the present embodiment, the frame member is a belt line reinforcement 21 extending in the vehicle front-rear direction X along the belt line BL at the window lower end edge of the side door 1.

According to the above configuration, the power swivel unit 13 is fixed to the beltline reinforcement 21 that is generally used in the conventional door structure, whereby the above-described mirror structure can be widely applied to the conventional door structure.

（8）

In the mirror structure of the present embodiment, the beltline reinforcement 21 is formed of an aluminum extrusion.

According to the above aspect, the beltline reinforcement 21 is made of an aluminum extruded material, and therefore, both the support rigidity of the electric rotating unit 13 and the weight reduction of the vehicle can be ensured.

（9）

In the mirror structure of the present embodiment, as shown in fig. 13, in a state in which the mirror main body 11 is located at the mirror use position P1, an inner side surface 11b of the mirror main body 11 facing the side door 1 is inclined toward the vehicle outer side with respect to a virtual line L1 which is orthogonal to the surface of the mirror 14 and passes through an inner end 11a of the mirror main body 11 in a plan view.

According to the above configuration, when the mirror main body 11 is located at the mirror use position P1, the inner side surface 11b of the mirror main body 11 is inclined outward with respect to the virtual line L1 orthogonal to the mirror surface, and thus the inner side surface 11b of the mirror main body 11 does not block the view when viewed from the cabin. This ensures the visibility as seen from the cabin to the maximum, thereby further improving the visibility.

（10）

In the mirror structure of the present embodiment, as shown in fig. 13, in a state in which the mirror main body 11 is located at the mirror use position P1, the thickness of the mirror main body 11 in the front-rear direction X becomes smaller toward the inner end 11a on the side of the side door 1 in the vehicle width direction Y from the intermediate position of the mirror main body 11 in the vehicle width direction Y in a plan view.

According to the above configuration, in the state where the mirror main body 11 is located at the mirror use position P1, the thickness of the mirror main body 11 in the front-rear direction X decreases from the intermediate position in the vehicle width direction Y toward the inner end 11a in the vehicle width direction Y, and therefore the inner side surface 11b of the mirror main body 11 does not block the view when viewed from the cabin. This ensures visibility as viewed from the cabin to the maximum, thereby further improving visibility.

The driving unit of the present invention may be other than the above-described electric rotating unit as long as the mirror main body 11 and the mirror base 12 can be moved between the mirror use position P1 and the storage position P2. For example, the driving unit of the present invention may be a unit driven by other driving force such as oil pressure or air pressure.
